Can anyone explain the uneven appearance of the regression line in this plot?

Pgfplots decomposes the regression line into small overlapping segments. Luckily it computes the parameters of the regression line and stores them into pgfplotstableregressionb and pgfplotstableregressiona, which allows one to draw the regression line as an ordinary single-stroke plot.
